Abstract: A semi-classical lattice Boltzmann model for quantum plasma flow is proposed based on the Wigner-Fokker-Planck equation coupled with Poisson’s equation. We derive the discrete quantum kinetic equation with operator terms series-expanded by Hermitian polynomials and present the semi-classical lattice Boltzmann equation that guarantees numerical stability. Numerical experiments are performed on electron fluid in dense quantum plasma, which are typically generated by a strong laser or present inside white dwarfs and supernovas. The different power spectra in electrostatic quantum fluid are analyzed through comparison with power laws. Our numerical modeling open a new avenue for studying the transport physics in semiconductors and the quantum optics as well as for astrophysical and laboratory-generated quantum plasmas.
